To all whom it may concern:

Be it known that we, EDUARD GOTTERIED CHRISTIAN LEOPOLD MEYER, of No. 40 Bornes'trasse, Hamburg, Germany, and HENRY FERDINAND JoHANNns Hour, of No. 128

Eimsbiitterlechausse, Hamburg, Germany,"

both subjects of the German Em eror, have invented certain new and usefu Improve:

ments in or Relating to Apparatus for Us;

This invention relates to' apparatus for use in loading'coal and similar-substances form and brought close to the loadin way In the intoships or the like; and it has for its object to enable the coal or. the other substances to betipped without breaking it, so that it willre'tain nearly its full value. v

According wagon, e. g. railway truck, loaded with coal or other material is run onto a swing platof the ship or the like to loa, ed, and may be discharged directly'into a suitable chute-emptying into the hold of the ship. The ho per of the chute is secured upon the deck o the ship to be loaded in order'that the chute may'share'all the movements of the said" ship and thus prevent "its lower "end I from being displaced relatively to the hesi. of coal or the like accumulated in the ho ingt-o ourinvention. Figs. 3 and 4 are side accordingjto ourinvention." Figs. 5 and 5 are respectivelyanelevation and a plan view of thejltubularychute and its hopper; and

a diagrammatic, viewi illustrating the forces operating inconnection with the modificat1on shown in Fig. 4.

fSimilar" characters of reference designate corresponding parts throughout the several.

views.

[,Refening now to the drawings, Figs. 1

and 2, a traveling stage or hoist B is mount-.-

v ed inany, known-manner in the framework A, asfto be vertically movable betweenguide rails O, by means of ropes s and a winch The platform P of the traveling stage or hoist.B is provided with a loose dle part p, carrying rails on which the to this invention an open,

Vhatchdrawings: Figures 1 and 2 are reuspectivelyside and front elevations of one; construction offloading-apparatus accord-1 5 elevations of modified constructions, also support the pensated in the rack -'attached ,tojthem. When the hoist B dedischarging the fla p opene slides into the hopper T of the tubuable part, p "of the ascent and movements railway truck Kis supported, the truck being held fast by the hooked catches or the like engaging with its axles. This moving .or tipping part 12 of the platform is provided at ts'rear end, at both sides, with "rollers 1' running on rails L on each side of the traveling stage, and moved up and down by means of a winch an (arranged in the winch cabin) operatingropes or chains 3' which are passed over guide rollers and at-.

tached to the axles of the rollers a".

During the forward travel of the rear end of the platform on'the rails ,L, the moving or tipping part p of the platform is pushed .outward over carrying rollers R and then rests on the swinging arm S, which is in engagement with the tipping platform and has its lower end guided on I both sides by shoes 9 sliding in guides f These guides aretoothed, so that .pawls is provided on't-he 'cros's piece of the'swinging arm S fix and swinging arm when pushed-out, whateverthe height .of the hoist B. During the ascentof the hoist B the pawls k are compelled 'to engage continuously in the guide f by means of a weighted lever s'cends, t-he pawlsk are released by a rod 11 operatedfrom the platform of the hoist, or from the drivers cab F.

The moving or tipping part- 3) of the platform'and the railway truck are moved outwardly by the winch w until the truck has reached the necessary outward positionfor the coal or the like which, on in the front end of the truck being lar chute which is formed of several telescopic sections 1 1 etc. The ropes' 8', serve to effect the swingmovement of the movplatform, and are wound the, winch a during the descent of the hoist. All the y are operated from the drivers' cab F23 The weig' t of the hoist itself and that of the' s'winging arm are nearly comusual manner by suitable counterbalance. weights (not shown).

The chute (Figs. 5, 5 and 5") rests firmly on the deck of the ship and consists of a hopper T to which are attached telescopic tubes r, r etc. To cause the tubes totelescope automatically, or the lower end of the tube to ascend, the hopper T is provided witha-flap f that swings back into the posiand unwound by tion f when coal or other material is thrown into the hopper. This flap operates a )awl 10 and ratchet 11 to rotate a gear 12 w llCll meshes with a gear 13 driving a chain 14 attached thereto. The chain 14 drives the miter gears 15 which drive a second chain sulficient room for the coal discharged fromthe truck.

When the coal in the hopper has fallen to the resultin normal level, that is to say, to the neck 0 the ho per, the flap f. again rises under the in uence of the counterweight Q, the operation being as follows:'

The lever carrying the said counterweight Q is fixed to the same shaft as that upon which the flap f turns so that with every movement of the said flap the counterweight Q is correspondingly moved. Loosely mounted about the said shaft ofthe flap f is the ratchet wheel 11 connected to the gear 12 which in turn meshes with the gear wheel 13 of the winding mechanism. As the pawl.

10,-engaging the ratchet 11, moves with the counterweight Q, it will rotate thesaid ratchet upon the forward movement and thereby gear 12 etc. As soon as the flap f is empty, however, the counterweight Q returns the said fiap, but the pawl 10 merely glides over the teeth of ratchet wheel 11 and does not advance the'same and thereby does not operate the winding mechanism. In

order to control the lower discharge outlet, the winding mechanism can also be operated by hand inturning a handle 18. To produce thesame effect on the platform 32 as is done by the swing lever S, the latter may be replaced by a jib c (Fig. 3); The jib is provided with rails'and is .displaceably mounted on the framework A and extends outwardly from same. On this jib the. movable platform p runs, by means of rollers 00 mounted on its front end, for the purpose of tipping the truck (not shown). This jib is set each time in accordance with the working altitude of the hoist B, and remains in thatposition until the work of loading is finish-ed,

In orderthat the level "of the jib may be attainedwith precision each time the hoist'i's raised, a stop is provided to arrest the travel ofthe hoist at any. desired point. The jib can be drawn in when the tipping apparatus is not working.

In plants where the platform 0 has only to'tip the truck from a certain constant level, namely that of the railway siding, the swing lever S is mounted on a fixed pivot and is was fitted with two corresponding rails L, on either side of the tipping platform 3). On these rails the'rollers 1, attached to the rear end of said. platform, run during the butward swing. The outward and return swing of the platform p and-truck K is effected by means of ropes or chains 8' attached at 7* and operated by a winch w, or, automatic-f ally, (Fig. 4) under the influence of the action of the weightof the load of coal in thetruck, and a counterweight G attached to theroller end of the tipping platform 72,] i

The rails -L receivingthe roller 0 in this modification are sha ed in a curve which" must be constructed'in accordance with the diagram 'of forces shown in Fig. 6. In such construction, during the outward; swing of the loaded truck, the horizontal force H in the direction of the moving platform out?" balances the vertical force V in such a man'- ner'that P P and the end of the-platform rollsupward in the rails L. 1 In the extreme outward position the curve is of such a-form" that H=V and therefore P =P,. During the emptying of the truck, the value-of .H

correspondingly falls'and P becomes :les's 1 without a swinging arm, is'raised to thei-desired altitude by means of the-winch w and the movable platform 2 is run out on the rails L by means ofithe winch w.- in which movement it first-slides over the rollers B,

and then rests on the swinging arm (sup ported inposition by the pawls). ,or runs along the track .on the jib Q) (Fig. 3). In this way the platform 37. reaches a projecting andinclined position, the slope being equal to. the angle bf slip for the coal. The

.workman standing by the .hopperT of the chute next allows the coal to slide into the chute, which is always-kept filled with coalup to the neckofthe hopper and is sup.- ported from the bottom of the ship, so that no coal can escape unlessthe bottom tube is raised. When additional coal enters the hopper, the lower end. of the tubular portion latforin e'nd runs of the chute is raised, by means of winding mechanism arranged on the neckof the hopv per, to such an extent that the 'oofitbah'eady present in the tube falls out and leaves room for an equal quantity to follow. When the railway truck is emptied, the tipping plat form ,1) is allowed to run back on the rails'L, and the swingingarm S (Figs. 1 and 2) is also returned to its original position. Then in the arrangement shown in Figs. 1 and 2,

the pawl 7" of the swing lever S is released; and the hoist, with the empty truck, is lowered by means of the winch w, and the railway truck run away from the tipping ap paratus. In the modification according to Fig. 3 the jib remains in itsextended position.
